V'IIIVPROVEM-ENT IIN PRI-VY-SEATS.

v`Specification forming part of Letters Patent No. 59,150, dated October 23, 1866.

To all whom it may concern.:

Beit known that 1,y ERNEST MANGEON, of Paris, in the Empire of France, have invented certain new and useful Improvements in Privy- Seats; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe accompan yin g drawings, making a part of this specification, in which- Figure l is a vertical transverse section, taken in the lille a a' of Fig. 3, and showing the privy-seat in a closed condition. Fig. 2is avertical transverse section taken in the line g! y of Fig. 3, and representing the privy-seat inan open condition. Fig. 3 is-a plan or top View, also representing the privy-seat in an open condition.

Similar letters ot' reference`indicate correspondin g parts in all the figures.

lt is desirable in water-closets or privies situated where a scarcity ot' water exists that some means other than repeated washings be employed to prevent the escape from the privy of the noxious gases or emanations engendered by the contents thereof, and that the privy should be so constructed that it may be easily and conveniently cleaned or purified when desired.

This invention is designed to accomplish these results 5 and it consists in a novel means of securing an air-tight joint between the hopper or casing ot' the privy and the cover thereof when the said cover is closed, and also in the employment ot' a valve so combined with the said cover and with the hopper or casing that when the cover is raised the valve will close the bottom vot' the said hopper, and thus prevent the escape of gases from the vault orv receptacle underneath the same, and when the said cover is closed the valve will be tilted to drop the impurities deposited thereon into the receptacle just mentioned 5 the invention being adapted to privies having seats of dit ferent kinds, and also to chamber-stools provided with removable vessels or receptacles underneath their seats, and its construct-ion being such that it may be washed out and cleansed when desired by a small quantity of water, and with -very little trouble.

To enable others to understand the construction and operation of my invention, I will prostitutes the upper portion ofthe apparatus, and

which has projecting downward from its rearmost partarectan guiar or other suitably-shaped rim, a, by means of which it is fitted upon the4 enlarged upperend of the conduit pipe or passage B, which communicates with a suitable vault or receptacle below. The forward part of the hopper is furnished with a flat bottom,

bfon which the person using the apparatus stands while so doing. The rearmost part of the said hopper is open at the bottom, as

shown at A', the said vopening being surrounded by a downwardly-projeeting flange or rim, o, which projects downward into the flange B, and has fitted upon its lower end another` annular rim, d, as shown more clearly in Fig.

2. The lower end of this lastmentioned rim d is closed by a valve, C, which is secured upon a transverse pivot, a', working in suitable bearings formed at opposite sides and upon the lower edge of the said rim (I.

The top or upper edgeot' the easing or hopper A is formed with an outwardly-projectin g rim, e, extending entirely around it and curved i in its cross-section in such manner as to form an annular groove or channel, B', in the said upper edge or top of the casing. This channel is filled with water, mercury, or other suitable liquid, in order to form an air-tight joint between the casing and the lid or coverthereof, as will be presently fully set forth.

D represents the lid or cover of the apparatus, which is hinged to the rearinost side of the casing A, as shown at f. Then this cover is closed its edge fits snugly upon the outer edge of the rim e, as shown at c in Fig. l, and situated at a Suitable distance within the said' edge of the cover is a downwardly-projecting annular rim, D', which extends down into the channel B near the innermost sidethereot,a11d below the surface of the liquid contained therein, as represented in the said Fig. l, so that the liquid et't'ectually seals the joint between the casing and the cover, and thus prevents the escape of gaseous emanations from the said casing or hopper A, when the cover thereof is closed, as just herein fully set forth, while the edge e of the cover, covering the liquid in the channel B, prevents the accidental displacement of the same.

Similar means may be employed, if desired, for formin gan air-tightjointbetween the flange a of the casing A and the Vupper end of the conduit pipe or passage B, as shown at g in Figs. l and 2.

Secured upon each end of the pivot a of the valve C is'a slotted arm, m, and sliding in suitable bearings attached to the inner side of the back of the casin g A, near the end thereof, isa vertical rod, n, the lower end of which is curved, as shown in dotted lines in Fig. 2, and is attached to the slotted arm by means of a pin, n', passing transversely through the slot in the said arm. i.

The upper end of each sliding rod u is con a connecting-rod or pitman, o", in such manner `that when the cover is raised up the slotted arm m will be lifted so as to bring the valve G into a horizontal position to close the opening A', as shown in Figs. 2 and 3, and thus prevent the escape of oii'ensive odors or noxions gases from the' passage B. It should be mentioned here that the forward side of the lower edge of the rim d is curved inward and upward, so as to form a shallow trough, d', in which the forward edge of the valve lits when the same is closed, and that the rearinost edge of the valve is alsoturned upward to form a similar trough, into which the rear edge ofthe said ri-ni iits, as at d. rlhe said trough, being filled with water, effectually seals the joint between the front andr rear edges of the valve and the adjacent edges ofthe rim d, when the valve is closed, as just set forth. When the said cover is turned down in closing the casing, as hereinbefore explained, the slotted arm m will be pushed downward and turn the valve C, attached thereto, into a vertical position, as shown in Fig. l, thus unclosing the opening A and allowing the impurities deposited upon the valve, when the cover D is raised to allow the apparatus to be used, to fall through the said opening into the conduit -pipe or passage B, and thence into the vault below. By these means the escape from the privy of gases or of noxious and offensive odors is effectually prevented, not only when the apparatus is closed, but also when it is opened for use. Furthermore, the invention may be applied, when desired, to water-closets having seats of any suitable kind, and also to chamber-stools pro vided with vessels or receptacles underneath their seats.

W hat I claim as new, and desire to secure by Letters Patent, is-

The combination Vof the cover D, valve C, and mechanism by which the position ot' the cover controls the position of the valve, so that when either is open the other is closed, all being arranged, in connection with the hopper A and conduit-pipe B of a water-closet or privy, substantially as herein set forth. i

In testimony whereof I have signed my name to this spcciication before two subscribing witnesses.

E. MANGEON.
